When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
Answer:
it is made up of two or more element
Given:
E = 7.3 × 10–17 Hz
h= 6.63 × 10–34 J•s
Now <em>E = hf</em>
where E is the energy of the photon
h is the Planck's constant
f is the frequency of the photon
Substituting the values in the equation we get
E= 7.3 × 10^-17 × 6.63 × 10^-34
<u>E= 4.8399 × 10^-50 J. </u>
